IMPROVEMENT IN ASH-SIFTERS.

Specification forming part of Letters Patent No. 158,110, dated December22, H74.; application filed November 13, 1874.

To all whom t may concern:

Beit known that I, JACOB MICHEL, of the city, county, and State of NewYork, have invented a certain new and Improved Ash- Sifter, ot" whichthe following is a specification:

rlliis invention is illustrated in the accompanying drawing, in whichFigure l is a longitudinal section. Fig. 2 is a transverse section inthe line x a", Fig. 2.

Similar letters indicate corresponding parts.

This invention consists in an ash-sitter, having a sieve made in twoparts, one of which is iixed, while the other is loose, and is connectedwith levers, by which it may be given a reciprocating motion. With theloose sieve and its levers is combined a spring, in suoli a manner as toaid in imparting motion, as hereinafter more fully specified.

In the drawing, the letter A designates the box of my sifter, which Iprefer to make of wood and B C are doors, with which the box isprovided. D designates the reciprocating sieve, which is arranged on aninclined plane. Opposite to the sieve is a platform or chute, ld, whichalso is inclined, but in a direction contrary to the sieve, the chuteserving to feed or direct the unsifted ashes upon the sieve, when thesame are dropped through the space occupied by the door G in the rootlof the box.

Vhen the ashes are dropped on the sieve D, and the sieve is given areciprocating motion, the ine ashes fall through and into a compartment,F, formed beneath the sieve, while the coal or coarse ashes roll oft',and are caught in a compartment, G, formed alongside the othercompartment. Either or bot-h of these compartments, F G, may be maderemovable from the box, and the compartment F has the form of a drawer,which may be removed at both ends, or on either side of the box. Thedraw F isheld by stops a, which swing` on the side 'of the box, or byany other suitable means. lThe compartment G in this example isstationary, access being had toit through the door B.

The compartments F G are preferably made of wood, and provided with alining, b, of metal, which is proof against the action of the ashes.

D designates the fixed sieve, which is secured to the inner sides of thebox A, and forms a support for the lower end' of the loose sieve D, theupper end of the loose sieve being held between a transverse plate, H,and lugs I, which are secured at that point. J designates levers, therespective inner ends of which are pivoted to the rear side of the plateH, while the outer ends are free, and project on opposite sides of thebox. From the levers J project arms K, which are subjected to the actionof a spring, L, which is secured at or near the bottom edge of the plateH, and has two branches extending, respectively, under the arms of thelevers. To the spring L and lever-arms K are connected lugs c, which areformed or secured on the loose sieve D, the connection being eii'ectedby interposing the lugs between the spring and arms, or in any othersuitable manner. The levers work in slots M formed in the side of thebox, and-their outer ends are made so that they can be convenientlygrasped by the hand. Vhen either or both of the levers are depressed,the loose sieve D follows the action thereof, and describes a downwardmovement; but, by the action of the spring L, the whole is immediatelyreturned, so that by repeatedly depressing the levers a rapidreciprocating' motion is imparted to the sieve without any materialexertion. In thefront of the sieves is a partition, N, of such lengththat it allows the coal falling from the sieve to pass under it, towhich partition is secured a series of shelves, O. These shelves areimmediately opposite the door B, so that they are convenient of access,and they are intended to receive kindling-wood, &c. By this means theutility of the sifter is materially increased.

IVhat I claim as new, and desire to secure by Letters Patent, is-

The combination, in an aslrsit'ter, of the rcciprocating sieve D, fixedsieve D', levers J, and spring L with the compartments F G,substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of November, 1874..

JACOB MICHEL.
